ABSTRACT

In humans, the prevalence of accessory maxillary ostium (AMO) ranges from 0 to 43%. Several conditions have been associated to the occurrence of an AMO, including recurrent maxillary sinusitis and a maxillary retention cyst, to name a few. This case describes a 22-year-old female with a visit to the Rhinology clinic with three AMOs, two on the right side and one on the left, all of which were located in the posterior nasal fontanelle.

Keywords: Accessory Maxillary Ostium (AMO), Maxillary sinus, Saudi Arabia.
